A method for making a reservation according to an exemplary embodiment of the present application is described below with reference to fig. 1 to 3. It should be noted that the following application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present application, and the embodiments of the present application are not limited in this respect. Rather, embodiments of the present application may be applied to any scenario where applicable.
The application also provides a reservation method, a reservation device, a target terminal and a medium.
Fig. 1 schematically shows a flow diagram of a reservation method according to an embodiment of the present application. As shown in fig. 1, the method is applied to online education, and includes:
s101, a first reservation request aiming at a target user is obtained, and the first reservation request carries a corresponding reservation time point and a reservation object.
First, it should be noted that, in the present application, a device for obtaining the first reservation request is not specifically limited, for example, the first reservation request may be obtained by an intelligent device, or the first reservation request may be obtained by a server.
In addition, in the present application, the smart device is not specifically limited, that is, the smart device may be any smart device, such as a mobile phone, an electronic notebook, a PDA, and the like.
The first reservation request in the application is used for reserving another party user who completes a teaching process with the user before the user gives a teaching in online education on a network. The target user generating the first reservation request is not specifically limited by the application. For example, the target user may be a student in online education on the internet, so that the student makes an appointment with a teacher with whom a lecture process is completed through a first appointment request. Alternatively, the target user may be a teacher in online education through a network, so that the teacher makes an appointment with a student who completes a teaching process through the first appointment request. Or, the target user can also be a manager in the network online education, so that the manager can make an appointment through the first appointment request for the purpose of completing teaching of students and teachers.
Optionally, the first reservation request of the present application carries a reservation time point and a reservation object generated by a target user. It is to be understood that the present application is not specifically limited to the reservation time point and the reservation target. For example, the reserved time point may be a certain day, a certain minute, or the like.
And S102, based on the reservation time point and the reservation object, locking operation is carried out in the distributed deployed database by using the distributed lock.
According to the method and the device, after the first reservation request is obtained, locking operation can be performed in a distributed deployed database by using a distributed lock based on the reservation time point and the reservation object carried in the reservation request. Further, the present application does not specifically limit the distributed deployed database, and for example, the distributed deployed database may be a cache type database, such as a Redis storage system (REmote DIctionary Server), a Memcached distributed cache system, and a Tair structured data storage system. Or, it may be a ZooKeeper distributed service framework system.
Alternatively, distributed locks are one way to control the synchronous access to shared resources between distributed systems. In the application, mutual interference can be prevented through mutual exclusivity of the distributed locks to ensure consistency, so that one reserved object can be executed by only one thread of one machine at the same time in a distributed system environment. That is to say, the method and the device can perform locking operation on the reserved time point of the reserved object by using the distributed lock in the distributed deployed database according to the reserved time point and the reserved object input by the target user.
Further optionally, the distributed lock in the present application may be a highly available acquire lock and release lock, which should have reentrant characteristics and a lock failure mechanism, so as to avoid deadlock problems that easily occur when locking in a distributed cluster.
In addition, the distributed deployed database in the present application should include the lecture resources or locations corresponding to each reservation object. And corresponding sub-teaching resources or sub-positions are required to be arranged at the teaching resources or positions of each reservation object along with different time periods. It is understood that, taking the target user as a student as an example, the reservation object can be a teacher in online education through a network. Since a teacher can complete the course of several classes of lectures at different time points on the same day, i.e. for example, teacher A can complete 5 classes of lectures between 9:00-10:00, 10:00-11:00, 14:00-15:00, 15:00-16:00, and 16:00-17:00 on the same day. In the distributed database, the teaching resources a corresponding to the teacher a should exist, and under the teaching resources a of the teacher a, the teaching resources 1 in the time period of 9:00-10:00, the teaching resources 2 in the time period of 10:00-11:00, the teaching resources 3 in the time period of 14:00-15:00, the teaching resources 4 in the time period of 15:00-16:00, and the teaching resources 5 in the time period of 16:00-17:00 are respectively corresponding. To ensure that locking operations can be performed with distributed locks at each of the lecture resources in the distributed database.
S103, when the locking operation is detected to be successful, reserving the target user based on the first reservation request.
Optionally, in the present application, based on the reservation time point and the reservation object, after the locking operation is performed by using the distributed lock in the distributed deployed database, the success of the locking operation may be further detected. The distributed lock is used for ensuring that one service can be executed by only one thread of one machine at the same time in the distributed system environment. That is, if the reservation object is reserved by another user at the reservation time point, the lecture resource at the time point is already occupied by the distributed lock corresponding to the reservation request generated by the other user, so that the lecture resource or location cannot be locked.
Further, when the locking operation is detected to be successful, no other user performs reservation on the reservation object at the reservation changing time point. Therefore, the method and the device can perform reservation for the target user based on the first reservation request generated by the target user after detecting that the locking operation is successful. The first appointment request is not specifically limited, for example, the user may input a course type, a course level, a course quantity, and the like in the appointment request.
In the application, after the first reservation request for the target user is obtained, a locking operation may be performed in a distributed deployed database by using a distributed lock based on a reservation time point and a reservation object carried in the first reservation request, and when it is detected that the locking operation is successful, reservation is performed for the target user based on the first reservation request. By applying the technical scheme of the application, whether the reservation is carried out for the target user can be determined by detecting whether the distributed lock is successfully locked at the teaching resource position corresponding to the reservation object and the reservation time point in the distributed database. Therefore, the problem of low efficiency caused by the fact that each user needs to be reserved manually in the related art can be solved.
Further optionally, in an embodiment of the present application, in S102 (based on the reservation time point and the reservation object, performing a locking operation using a distributed lock in a distributed deployed database), a specific embodiment is further included, as shown in fig. 2, including:
s201, a first reservation request aiming at a target user is obtained.
And S202, determining the teaching resources in the database corresponding to the reservation time points according to the reservation time points and the reservation objects and aiming at the teaching resources in the reservation objects.
Optionally, the distributed deployed database in the present application should have teaching resources corresponding to each reservation object in online education. For example, when a certain online education system includes 3 teachers and 5 students, the database should include user teaching resources corresponding to the 3 teachers and 5 students, respectively. Similarly, each user should have a corresponding course time point for each course under the teaching resources. As can be appreciated, the respective lesson time points correspond to respective appointment time points.
And S203, locking the teaching resources by using the distributed lock.
Further, for example, the distributed database includes a teaching resource a corresponding to teacher a, a teaching resource B corresponding to teacher B, a teaching resource C corresponding to teacher C, a teaching resource 1 corresponding to student d, a teaching resource 2 corresponding to student ant, and a teaching resource 3 corresponding to student xin. When a first reservation request which is generated by a student D of a target user and carries a reservation time point of 2019.6.6 days 10:00 and a reservation object of a teacher A is received. And determining the teaching resources in the database as teaching resources A through the reservation time points and the reservation objects. Furthermore, the present application may perform a locking operation on the teaching resource a by using a distributed lock.
And S204, when the distributed locking operation is detected to be successful, adding teaching mark information of the target user into the teaching resources, wherein the teaching mark information is used for extracting the teaching information of the target user in the online education.
Optionally, after the distributed lock is used for locking the teaching resources, teaching mark information for the reservation user can be further added to the teaching resources when the locking operation is detected to be successful. It should be noted that, when it is detected that the locking operation using the distributed lock is successful on the lecture resource, since the distributed lock has a characteristic that only one thread can be occupied at the same time, it means that the reservation object is not reserved by other users at the reservation time point. Furthermore, the teaching mark information used for extracting the teaching information of the target user can be added into the teaching resource, so that the teaching information corresponding to the reservation user can be directly obtained according to the teaching mark information after the reservation object receives the successful reservation notification message of the target user. Therefore, the target user can be known in advance, and better teaching efficiency can be achieved in class.
Furthermore, the teaching mark information is not specifically limited in the present application, for example, the teaching mark information may be teaching material information required for extracting the course of the target user, and the teaching mark information may also be teaching record information used for extracting the course of the target user in history, and the like. It is to be understood that the instructional mark information may be an identifier for extracting instructional information of a target user in the network online education.
And S205, reserving for the target user based on the first reservation request.
And S206, after the successful reservation of the target user is detected, generating reservation success information, wherein the reservation success information carries teaching mark information.
And S207, after the second preset time period of the reservation success information is generated, transmitting the reservation success information carrying the teaching mark information to a reservation object.
Optionally, after the reservation is successfully made for the target user, the reservation success information carrying the teaching mark information may be sent to the reservation object. So that the reservation object can know that the reservation object gives lessons to the target user at the reservation time point according to the reservation success information. Meanwhile, the application is applied to the field of online education of networks, namely, the reservation object and the reservation user complete the teaching process through remote communication, so that the problem that the reservation object (such as a teacher) and the reservation user (such as a student) are not mutually understood due to the unfamiliar state and the teaching efficiency is not high is avoided. The reservation object in the application can also extract the teaching information about the target user according to the teaching mark information aiming at the target user in the reservation success information. Therefore, the teaching progress, character characters, teaching weak points and the like of the target user can be known before the teaching process, and the course teaching direction is specifically deployed, so that the teaching efficiency is improved.
It should be noted that, in the present application, the position of the reservation object for extracting the teaching information according to the teaching mark information is not specifically limited. For example, the reservation target may extract corresponding teaching information from the corresponding information database according to the teaching mark information. The reservation object can also extract corresponding teaching information from the database according to the teaching mark information.
And S208, when the locking operation aiming at the teaching resources is detected to be successful, acquiring the identification number of the teaching resources, wherein the identification number is used for representing that the teaching resources are locked.
Optionally, after the locking operation for the teaching resources is detected to be successful, the reservation success information carrying the teaching mark information may be generated, and the identification number of the teaching resources may be further obtained. The identification number of the teaching resource can be used for representing that the teaching resource is locked, that is, the reservation object is reserved by other reservation users at the reservation time point.
S209, the identification number is recorded in the reserved list.
S210, when a second reservation request carrying a reservation time point and/or a reservation object is acquired in a first preset time period after reservation is carried out on a target user, the second reservation request is processed based on a reserved list.
Optionally, in the present application, in order to avoid a problem of resource waste caused by locking an object to be reserved at a certain time point for many times when the object to be reserved is reserved by other reservation users at the certain time point. In the method, when it is detected that a second reservation request related to the reservation time point and/or a reservation object is received again within a first preset time period after reservation is performed for a target user, a distributed lock is not directly used in a distributed deployed database to lock a teaching resource, but a pre-generated reserved list is firstly inquired, and the second reservation request is processed according to an inquiry result.
Further, when the identification number of the teaching resource exists in the list according to the reserved list, the reserved object is judged to be reserved by other users at a certain reserved time point. Furthermore, the reservation time point corresponding to the identification number of the teaching resource is continuously inquired. It can be understood that, when it is detected that the reservation object and the reservation time point in the second reservation request are both consistent with the reservation object and the reservation time point corresponding to the identification number according to the identification number of the teaching resource, it is determined that the reservation object is reserved at the reservation time point. And further generates judgment information which cannot be reserved. Similarly, when the reservation object and the reservation time point in the second reservation request are detected to be inconsistent with the reservation object and the reservation time point corresponding to the identification number according to the identification number of the teaching resource, the reservation object is determined not to be reserved at the reservation time point. And then according to the second reservation request, reserving the corresponding user.
It should be noted that the reserved list in the present application is time-limited, that is, after the reservation course is completed, the reserved list needs to be updated to ensure that the latest reservation request is processed. For example, it may be updated once a week or once a month. Further, in order to avoid the disadvantage that the second reservation request is repeatedly processed according to the reserved list after the target user is reserved according to the first reservation request, when the second reservation request is received after the target user is reserved in the application, it may be first detected whether the second reservation request is the reservation request received within a first preset time period after the target user is reserved. And processing the second reservation request based on the reserved list after the determination.
Optionally, the first preset time period is not specifically limited in this application, and may be, for example, 7 days or 30 days.
In the method and the device, after the first reservation request for the target user is obtained, based on the reservation time point and the reservation object carried in the first reservation request, a distributed lock is used for locking at the teaching resource in the database, and after the reservation for the target user is successfully made, the teaching mark information of the target user is added into the reservation success information. By applying the technical scheme of the application, after distributed locking is successfully utilized at the teaching resources corresponding to the reservation objects and the reservation time points, the teaching mark information of the target user can be added into the reservation success information informing the reservation objects, so that the reservation objects can acquire the teaching information of the target user according to the mark information. Therefore, the problem of poor teaching efficiency caused by unfamiliarity between students and students in online network education in the related technology can be solved.
Further optionally, in an embodiment of the present application, in S102 (based on the reservation time point and the reservation object, performing a locking operation using a distributed lock in a distributed deployed database), a specific embodiment is further included, as shown in fig. 3, including:
s301, a first reservation request for a target user is acquired.
S302, acquiring a target distributed lock;
and S303, releasing the target distributed lock when a third time period passes, wherein the third time period is determined based on the reserved time point.
Optionally, after the first reservation request of the target user is obtained, the target distributed lock may be released after a third time period elapses by setting a timer for releasing the target distributed lock after the third time period elapses on the target distributed lock. It can be understood that the purpose of setting the timer on the target distributed lock is to prevent the problem that the reserved object cannot be reserved continuously because the distributed lock is always locked on the teaching resource due to a fault, a conflict and the like. For example, when the reservation target completes the lecture process at 10:00 with the target user, the distributed lock of the lecture resource corresponding to 10 points in the reservation target is not automatically released due to a system failure, and the like, so that the reservation target cannot be locked again at the corresponding lecture resource position at 10 points. That is, the reservation target cannot be reserved by other users at 10 o' clock time period of the remaining days all the time. Therefore, in the present application, a timer for releasing the target distributed lock after the third preset time period may be added to the distributed lock, so that the distributed lock automatically releases the distributed lock after the third preset time period. Thereby avoiding the resources of the lecture from being occupied all the time.
Further, the third preset time period in the present application may be a time period obtained based on a reserved time point. For example, when the preset time point is a time point that is different from the time point when the target distributed lock is acquired by 24 hours, the third preset time period may be a time period with a duration of 24 hours. Thereby ensuring that the target distributed lock can be automatically released after the reserved time point is reached. Still alternatively, in the case where the preset time point is a specific time point (for example, 2019.6.6 days 10: 00), the third preset time period may also be a time period that is 1 hour before the preset time point since the target distributed lock is acquired (for example, 2019.6.5 days 18: 00) (that is, a time period that is 15 hours long). The third preset time period is not specifically limited in the present application.
And S304, based on the reservation time point and the reservation object, locking operation is carried out in the distributed deployed database by using the target distributed lock.
S305, when the locking operation is detected to be successful, reserving the target user based on the first reservation request.
S306, detecting the reserved times of the reserved object in a fourth preset time period, wherein the fourth preset time period is a time period including a preset time point.
Optionally, the problem of low teaching efficiency caused by that the same reservation object is reserved in a large amount in a short time in online education through a network is avoided. In the application, after the reservation is performed for the reserved object at the corresponding time point according to the first reservation request, the reserved times of the reserved object in a fourth preset time period can be further detected.
